Boat or plane ? Depends on tide or wind speed/direction. Measured against what reference too, earth's rotation.

Are you factoring in the 20 minutes when you sit shamefaced in the back of a police car pretending that you had no idea how fast you were really going in a 40mph zone?

Are you factoring in the deceleration from the 2,700,000 mph we are travelling through space?

ok, if you went at 100mph for the first half hour, how fast would you need to go for the second half hour to average 80

8 more MPH and it would take minus thirty years.

Conveyor belts? Where we're going we won't need conveyor belts.

60mph obvs*. Is this like those competitions on the tellybox designed I presume to entice stupid people into thinking that they are the only ones who know the answer to questions like this?

* Assuming immediate deceleration from 100 to 60...

It'd have to be a road bike surely..? You couldn't maintain speed on a MTB.

Viz

Drivers - avoid being nicked by the new average speed cameras by doing 90mph for 2 minutes then stopping for a spliff

I'm trying to think of a clever answer, but what would happen if you sampled the speed every mile rather than every minute?

The tyre turning thing obviously affects it.

Assuming mph is miles per hour not metres per hour - the defintion of (constant) 80mph is travelling 80 miles in an hour. So how can the answer not be one hour? What am I missing?

Or is this an oblique reference to Zeno's dichotomy paradox?

If I go 80mph for one hour, how far have I gone? ** Mind Blown **

how far have I gone?

depends what route you take - it your on the M25 you'll be 37 miles away from where you started (and in quite a bit of trouble when you open the post in a few days time)

if its around the circumference of a 25 mile wide circle you'll have gone nowhere ...fast.

But you've stil gone 80 miles.

But you've stil gone 80 miles.

but how then do you measure the distance between two places?

Indeed - you'd be smarter to go the other way round - you'd get there in less than half the time

yes, always shorter out of the sun, as the crow flies

Indeed. You're mixing a linear geometry (nearly flat plane) with a non-linear one (the road network). So you get these apparent paradoxes.
